This Missa in G minor is the only surviving work in this genre by Johann Hugo von Wilderer; his output as Kapellmeister at the Electoral Palatinate court, which resided in Mannheim from 1720 onwards, was mainly devoted to opera. The three-part Kyrie, the through-composed Gloria, and the partly obbligato instrumental writing show the influence of the early Neapolitan mass style. The music-historic significance of the Missa is firstly that it is an important example of the church music performed around 1700 at the Electoral Palatinate court, but above all that Bach evidently used it as a source of inspiration for the Kyrie of the Mass in B minor, as shown, for example in the form of the Adagio introduction of the Kyrie I in both works.
